On the top of the two triangular support plates, limit blocks are fixedly installed, and the outer surfaces of the two drive rods are movably inserted into the interiors of the two limit blocks. On the top of the two triangular support plates, two movable grooves are opened. On one side of the outer walls of the two screening frames, two moving grooves are opened. The inner surfaces of the four moving grooves are movably embedded with L-shaped sliders, and a sieve plate is in contact between the tops of the four L-shaped sliders.

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1 - 4As shown in the figure, the utility model provides an automatic material screening device for building construction, which includes two screening frames 1. On one side of the outer walls of the two screening frames 1, triangular support plates 2 are fixedly installed. On the top of the two triangular support plates 2, driving motors 3 are fixedly installed. On one side of the outer walls of the two driving motors 3, driving rods 4 are fixedly installed. On the outer surfaces of the two driving rods 4, two semi-circular convex blocks 5 are fixedly sleeved. On the top of the two triangular support plates 2, limit blocks 6 are fixedly installed, and the outer surfaces of the two driving rods 4 are movably inserted into the interiors of the two limit blocks 6. On the top of the two triangular support plates 2, two moving grooves 7 are opened. On one side of the outer walls of the two screening frames 1, two moving grooves 8 are opened. In the inner surfaces of the four moving grooves 8, L-shaped sliders 9 are movably embedded. A sieve plate 10 is in contact between the tops of the four L-shaped sliders 9.

[0025] The effect achieved by the entire Embodiment 1 is that when it is necessary to screen the sand used in building construction, start the two driving motors 3 to drive the two driving rods 4 to rotate inside the two limit blocks 6, thereby driving the four semi-circular convex blocks 5 to rotate on the two driving rods 4. Since two moving grooves 8 are opened on one side of the outer walls of the two screening frames 1, and the four L-shaped sliders 9 in contact with the bottom of the sieve plate 10 are all movably embedded in the four moving grooves 8, then the four semi-circular convex blocks 5 are intermittently in contact with the bottom of the sieve plate 10. Thus, when the four semi-circular convex blocks 5 rotate at a constant speed, the sieve plate 10 can be intermittently lifted up, thereby having a vibrating effect on the sieve plate 10, causing the sieve plate 10 to drive the four L-shaped sliders 9 to move up and down in the four moving grooves 8, and screening the sand on the sieve plate 10. It is not necessary for workers to screen the sand, reducing the workload of the workers, improving the use effect of the screening device, and thus improving the work efficiency.

[0026] Embodiment 2, as Figures 2 - 4 shown, on the tops of the four L-shaped sliders 9, fixing blocks 11 are fixedly installed. Inside the inner surfaces of the four fixing blocks 11, fixing bolts 12 are threadedly connected. On the top of the sieve plate 10, four fixing holes 13 are opened, and the outer surfaces of the four fixing blocks 11 are movably inserted into the interiors of the four fixing holes 13. On the outer surfaces of the four fixing bolts 12, lock sleeves 14 are movably sleeved, and the bottoms of the four lock sleeves 14 are in contact with the top of the sieve plate 10. On the top of the sieve plate 10, a surrounding frame 15 is fixedly installed. Between the outer surfaces of the two triangular support plates 2, a collection frame 16 is in contact. At the bottom of the inner wall of the collection frame 16, two strip-shaped grooves 17 are opened. In the inner surfaces of the two strip-shaped grooves 17, strip-shaped sliders 18 are movably embedded. Between the tops of the two strip-shaped sliders 18, a collection box 19 is fixedly installed.

[0027] The effect achieved by the entire Embodiment 2 is that since four fixing holes 13 are provided at the top of the sieve plate 10, and the sieve plate 10 is sleeved on the four fixing blocks 11 through the four fixing holes 13. Also, when the four fixing bolts 12 are threadedly connected to the interiors of the four fixing blocks 11, the four locking sleeves 14 are sleeved on the four fixing bolts 12, and then the four fixing bolts 12 are screwed downward until the four locking sleeves 14 contact the top of the sieve plate 10 and are stuck outside the four fixing holes 13, thereby limiting the sieve plate 10 on the four L-shaped sliders 9. The disassembly and assembly are simple, facilitating the screening of sands with different thicknesses during construction. Secondly, the screened sand falls onto the collection frame 19 along the sieve plate 10. Since the two strip-shaped sliders 18 installed at the bottom of the collection frame 19 are both movably embedded in the interiors of the two strip-shaped grooves 17, it is convenient for the staff to use the sand in the collection frame 19, further improving the use effect of the screening device.

[0028] Working principle: First, during the construction process and when making concrete, according to the thickness of the sand to be screened, a specific sieve plate 10 is placed on the four L-shaped sliders 9, and the fixing blocks 11 on the four L-shaped sliders 9 are completely inside the four fixing holes 13. Then, under the action of the four fixing bolts 12 and the four locking sleeves 14, the sieve plate 10 is limited on the four L-shaped sliders 9. Then, the two drive motors 3 are started to drive the four semi-circular convex blocks 5 to rotate on the two drive rods 4, and the four semi-circular convex blocks 5 intermittently contact the bottom of the sieve plate 10, so that the sieve plate 10 drives the four L-shaped sliders 9 to move up and down in the four moving grooves 8, thereby achieving the effect of vibrating the sieve plate 10, and then the sand on the sieve plate 10 can be screened, enabling the fine sand to gradually fall into the collection frame 19. And under the action of the two strip-shaped sliders 18 and the two strip-shaped grooves 17, it is convenient for the staff to use the screened sand. Generally speaking, by using this screening device to screen the sand, the accuracy and excellence of the concrete mix ratio can be ensured. The entire screening process is automated, without the need for manual sand screening by the staff, reducing the workload of the staff and improving the use effect of the screening device, thereby improving the use effect of the automatic screening material device for building construction.

[0029] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
